Cation exchange capacity [C.E.C.] of the Rajasthan [India] Canal Soils was recognized in close correlation with clay, silt and organic matter on contents respectively. The contribution of clay was dominant to the C.E.C. followed by O.M. and silt contents. Multiple regression equation relating clay and O.M. content. (C.E.C. = 0.751 clay + 5.69 O.M.) with the C.E.C. of soils was found more suitable than that including silt content, and can be used precisely, for prediction of C.E.C. of these soils.
